How to set optical drive speed
The speed of the optical drive is set separately for CD-ROM and DVD, and is reset at reboot and resume from suspend.
- CD-ROM: use
# hdparm -E numor
# eject -x num.
- DVD: use
# speedcontrol -x num(sourcecode here).
For recent ThinkPad models running kernels older than 2.6.15, this may require the libata pass-through patch.
